Hemi swap oil pan questions
I'm not sure about mixing the components since the steering box mounts in the same place on the K frame and the tie rod ends should be similar. HOWEVER, the center link and Pitman/Idler are different. The 72 and older connect with the center link from the bottom (like we have in our pictures above), the 73 and up is reversed, with the arms connecting from the top. Here is a picture of a 72 and prior Idler arm on the left and a 73 and up on the right. I believe as long as the pitman/Idler/center link are all matched the tie rod ends are fine with either combination. Now I'm going to guess that with the new Holley parts based on the 73 and up spool mount K frame, the engine may sit a little higher and with the bolted ends of the center link facing down the center link may be lower, so there may be no oil pan fouling issue if using all of the 73 and up pieces, but as I said, that is just a guess on my part. If I had a 73 and up center link here I would try it.
